a dilation of figure 1 with scale factor 12 then a reflection
О
a dilation of figure 1 with scale factor 12 then a translation
a dilation of figure 1 with scale factor 3/2 then a translation
a dilation of figure 1 with scale factor 3/2 then a reflection

Option (4)

Step-by-step explanation:

Length of segment between two points and is given by,

d =

From the figure attached,

Distance between A(0, -3) and B(3, 0) =

AB =

Distance between A'(-3.5, -4.5) and B'(-8, 0)

Length of A'B' =

A'B' =

Scale factor for dilation =

Therefore series of transformations will be,

A dilation of figure 1 with scale factor of and then a reflection.

Option (4) will be the answer.

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.

hi how are you doing today, if you need just ask me.
